It's not really our place to say if it makes sense for Arch to compile with valgrind flags turned on. It really depends on how they use Python in their Linux distribution and what their own goals are.

I already asked the package maintainers about this, I just wanted to know if my understanding about what --with-valgrind means is correct or if there are good reason to turn it on (except debugging Python).

If they are good defaults, why aren't them the default?

That's a question for Arch Linux and not us. 

I probably didn't explain myself correctly: I was asking why they're not the default values for Python configure script...
